Primefaces 5.2

Found out decision. In order to hide zero values you should create js script in your xhtml file and then bind this script to model with org.primefaces.model.chart.BarChartModel.setExtender method.

<script>
        function extender() {
        this.cfg.seriesDefaults = {
        showMarker: true,
        renderer: $.jqplot.BarRenderer,
        pointLabels: {show: true, location: 'n', ypadding: 0, hideZeros: true}
        };    
    }
</script>

Java Class:

BarChartModel model = new BarChartModel();
model.setShowDatatip(false);
model.setShowPointLabels(true);
model.setExtener("extender");

xhtml

<p:chart type="bar" model="#{'javaClassController.getModel()'}"/>

Result should look like this:
